a: clock

Lever it out

b: outside temp ( radio channel is illuminated correctly but temp is low)

D8: Lever it out
D9: Pry off the panels either side of the display, undo the 4 torx screws, then pull the unit out

c: all bulbs for air con display

D8s Lever out the small panels at the end of the row of buttons+display, undo the 4 torx screws, remove the whole row of buttons+screen
D9s Remove the display

then remove the stereo (including fascia if an aftermarket stereo's been fitted)

then pull the a/c display out
